Description

Multi-airbag inflation explosion-proof inner tube of automobile

Technical Field

The application relates to the field of tires, in particular to an explosion-proof tire, and relates to a multi-airbag explosion-proof tire.

Background

Flat tire refers to a phenomenon in which a tire collapses in an extremely short time due to sudden loss of air from a rupture. The tire burst is one of frequent accidents of the automobile in summer. Most of which are caused by improper maintenance of the tires by the vehicle owners. The statistical data show that 10% of traffic accidents on motorways are due to tire failure, and that one term of tire burst accounts for more than 70% of the total number of accidents caused by tire failure.

When the tire is punctured by a nail or other sharp objects and is not punctured temporarily, the tire can be punctured, and the tire can be punctured, so that the tire burst is caused. The tire has over high air pressure, and because the automobile runs at high speed, the temperature of the tire rises, the air pressure rises along with the temperature of the tire, the tire deforms, the elasticity of a tire body is reduced, the dynamic load of the automobile is increased, and internal cracking or tire burst can be generated if the automobile is impacted. This is also the reason why the flat tire accident may be intensively exploded in summer. The tire pressure is insufficient, when the automobile runs at high speed (the speed exceeds 120km/h), the tire pressure is insufficient, so that the tire body is easy to generate 'harmonic vibration' to cause huge resonance acting force, and if the tire is not firm enough or has 'hurt', the tire is easy to burst. Furthermore, insufficient air pressure increases the amount of tire subsidence, which tends to cause sidewall contact during sharp cornering, which is the weakest part of the tire, and which also leads to tire burst. The tire is seriously worn after being used for a long time, no patterns (or too low patterns) exist on a crown, a tire wall becomes thin, the tire becomes a conventional 'plain tire' or a rugged 'weak link', and the tire can be burst due to the fact that the tire cannot bear high pressure and high temperature of high-speed driving.

In the conventional run flat tire, also called run flat tire, the sidewall of the inflated tire is a main part for supporting the weight of the vehicle, and particularly, in some tires with a large aspect ratio (aspect ratio is the ratio of the height to the width of the tire), the sidewall is very "thickened". However, the existing run-flat tires are all vacuum tires with a single structure, and the inner tube structures used by some special vehicles cannot be well adapted.

Disclosure of Invention

The application aims to provide a multi-airbag inflation explosion-proof inner tube to solve the problem of air leakage and explosion prevention of a tire with the inner tube in the prior art.

The embodiment of the application is realized as follows:

the utility model provides an explosion-proof inner tube is aerifyd to many gasbags of car, including aerifing the rubber matrix that the inflation type provided the supporting effect, be equipped with a plurality of lamellas of separating into a plurality of gasbags with the rubber matrix in the rubber matrix.

The rubber tire is internally provided with an inflation and deflation system, the inflation and deflation system comprises a plurality of independent inflation tubes communicated with corresponding airbags and an air faucet penetrating out of the rubber tire, each inflation tube is communicated with the air faucet, and a check valve for supplying gas to enter each inflation tube in a one-way mode is arranged in the air faucet.

The invention relates to an explosion-proof inner tube structure, which is characterized in that an inner tube structure and an outer tube structure are adopted on a plurality of existing medium-sized and large-sized vehicles due to load requirements, so that the inner tube structure and the outer tube structure have good stability under large load. Although the existing vehicle mostly adopts a vacuum tire structure, the vacuum tire cannot ensure good stability in a long-time heavy load state, and needs a special structural design so as to be filled with gas with higher pressure, which results in higher cost.

However, the existing tire structure with an inner tube has poor wear resistance and poor external protection capability compared with a vacuum tire due to structural specificity. The tubeless tyre does not use an inner tube, and air is directly filled into the inner cavity of the outer tyre, so that the friction between the inner tyre and the outer tyre is eliminated, and heat is directly dissipated from the rim, and the temperature is reduced by more than 20% compared with the common tyre. The tubeless tire is safer than the tubeless tire, the vacuum tire is more wear-resistant, and the oil is saved. Therefore, in order to improve the safety performance of the conventional tire structure with an inner tube, a tire structure with multiple air bags is provided.

That is, in order to increase safety performance, a plurality of isolation structures are arranged on the existing inner tube at intervals to form a plurality of independent chambers, and then the chambers are inflated to form air bags with consistent air pressure. And the inner tire is internally provided with uniform inflation equipment for inflation and deflation, so that the safe driving process of a single air bag can be ensured even if the single air bag is punctured.

However, the existing multi-air-bag inner tube mostly adopts a uniform air supply structure, once a single air bag is broken or punctured, other air bag structures can also be slowly deflated, and the running can only be maintained for one time. The invention provides a multi-air-bag inner tube, which improves the safety by adopting an inflation and deflation device with a multi-air-tube structure. When the inflatable air bag is inflated, only a single air nozzle needs to be aligned to inflate, and the air bags are inflated simultaneously, so that the inflating time is shortened, and the problem that the air pressure difference value of the air bags close to the inflating opening and far away from the inflating opening is large is solved, and the practicability is improved. Because the existing integrated inflation system is provided with the one-way valve on the flap, once the air starts to pass through, the air needs to pass through the other air bag after the first air bag reaches a certain air pressure, and then delay is generated. If more chambers are arranged, the uniform air pressure of each chamber cannot be ensured, and the check valve has certain air pressure loss.

In order to avoid the problems, the inflation and deflation system provided by the invention has the advantages that the inflation tube structure which is used for independently inflating each air bag is arranged, so that the inflation and deflation efficiency can be effectively ensured, and a certain air pressure difference can be avoided. The air is inflated through the uniform air nozzle, meanwhile, each inflation tube is injected, then high-pressure air rapidly enters each air bag, even if a certain distance interval exists, the difference of the air flow speed is negligible compared with the difference of the small distance because of the large air pressure.

On the other hand, the multi-airbag inflation explosion-proof inner tube of the automobile comprises a rubber tube body which is inflated and expanded to provide a supporting effect, a plurality of flaps which divide the rubber tube body into a plurality of airbags are arranged in the rubber tube body,

the internal gassing system that fills that is equipped with of rubber child, fill gassing system include many alone with the gas tube that corresponds the gasbag intercommunication and wear out the outer air cock of rubber child, every gas tube all communicates with the air cock, all be equipped with the check valve that the one-way entering of gas feed corresponds in the gas tube.

The specific position of the one-way valve is improved, and in order to improve the stability, the one-way valve is independently arranged in each inflation tube so as to ensure that the air leakage of a single air bag cannot cause great influence on other air bags. If only set up in air cock department, its cost is lower, nevertheless in case damage leads to whole inflation and deflation system all can leak gas.

Further, the inflation and deflation system further comprises an air distribution pipe arranged on any flap, the inflation pipe is communicated with the air distribution pipe, and the air nozzle is arranged on the air distribution pipe.

The air distribution pipe is used for communicating all the inflation pipes, a cavity is arranged in the air distribution pipe, when high-pressure air enters the air distribution pipe from the air tap, the whole air distribution pipe can be quickly filled, and then the high-pressure air enters each inflation pipe from the air distribution pipe. The air distributing pipe is arranged on a single flap, the whole inner tube is of an annular structure, the cross section of the inner tube is of a similar circle, the flap is of a plane structure perpendicular to the axis of the inner tube, and the material of the flap is the same as that of the inner tube. And the general air cock sets up and is being close to inner circle one side and wear out from the inner circle, when installing on wheel hub, its air cock also wears out from the air cock through-hole that is equipped with on the wheel hub to the side passes the spoke and outwards is convenient for the gassing. The air distribution pipe is arranged between the valve sheet and the inner tube wall, or a through hole is arranged in the corresponding valve sheet for placing the air distribution pipe.

Furthermore, when the total number of the air bags is even, the number of the inflation tubes is equally distributed on two sides of the air distribution tube and penetrates through the flaps from two ends to be communicated with the corresponding air bags in a nearest path;

when the total number of the air bags is odd, the inflation tubes are distributed on two sides of the air distribution tube, one more inflation tube is arranged on one side of the air distribution tube, and the inflation tubes arranged on the side are communicated with the air bags at the farthest ends of the air distribution tube.

The specific path is limited, in order to ensure that the inflation is more convenient, only one air distribution pipe is arranged in the whole inner tire, and each air bag is correspondingly provided with a single inflation pipe, so that the optimal arrangement mode is that the inflation pipes are symmetrically arranged. For example, the whole inner tube is divided into eight air bags, two ends of the air distribution pipe are equally divided into four air bags, and four inflation pipes are arranged on one side of the air distribution pipe. When the air distribution tube is divided into nine air bags, one side of the air distribution tube is provided with four air bags, and the other side of the air distribution tube is provided with five air bags, so that one side of each five air bag is provided with one more inflation tube.

Once the air release is needed, the nozzle is directly opened, and the internal air is sprayed outwards at a certain flow rate. When one of the air bags is damaged and leaks, the gas in the other air bags can not leak through the exhaust pipe or the inflation pipe, the whole exhaust pipe is filled with the gas with the same pressure, but the gas in each air bag is limited to be discharged from the air bag by the check valve in each air bag.

The structural layout of the two exhaust pipes is similar to the principle of the air distribution pipe, a structure with a cavity is arranged in the same air bag, and the structure is connected with the two exhaust pipes with the same length and extends towards the two ends respectively. If the number of the air bags is odd, the number of the air bags communicated with any one exhaust pipe is increased by one.

It should be noted that the nozzle is the same as the existing valve core structure, and the valve core structure of the corresponding type can be adopted according to the limited air pressure of the actual product.

Furthermore, the inner wall of the rubber tire body protrudes inwards to form a strip-shaped rib structure, and the exhaust pipe is arranged in the rib.

Further, the contact surface of the spray pipe and the rubber tire body is provided with an annular outer edge; the spray pipe penetrates out of the outer portion of one end of the rubber tire body, and a compression ring used for improving the sealing effect is arranged in a matched mode through the external thread.
